I'm planning to build a PC for gaming, live streaming and making YouTube videos but gaming is the most important thing. I will be gaming at 1080p and playing games like Titanfall, Next car game, assassin's creed black flag, dirt showdown and Grid Autosport. I want to be able to play these games on high/ ultra settings at 30FPS but 60 would be nice. My budget is less than £600. I would like to mention I don't want to overclock and the differences in each system is ether the GPU or CPU. What system is better for gaming and would last the longest before needing upgraded?
